JEE Main Chemistry question
What is the total score for the correct statement(s) below?
(a) [Score 4] A stronger oxidizing agent has a lower (standard) oxidation potential.
(b) [Score 1] A solution of aqueous cannot be stored in a Zn vessel.
(c) [Score 3] In a concentration cell made of Ag electrodes, the half-cell having the lower will behave as the anode.
(d) [Score 2] will remain constant during the electrolysis of aqueous solution using a Pt electrode as the anode and a Cu electrode as the cathode.
Solution
(a) is correct: a stronger oxidizing agent has a greater tendency to be reduced (higher reduction potential), which is equivalent to a lower (more negative) oxidation potential. (b) is correct: V is far lower than V, so Zn spontaneously reduces
